Taxes - Seller is typically responsible to pay the documentary stamps on the sale. This fee is charged by the county where the property is located, and in most counties the charge is $0.70 per $100 of the sales price. For example, the documentary stamps on the a $100,000 sales price will be $700.
Prorations - tax and homeowners association dues are usually prorated at closing, so that both the buyer and the seller pay their respective shares of the expenses, based on their ownership of the property during the year. For example, if the closing occurs in the middle of the year, the seller will be responsible for half of the real estate taxes, and the buyer will be responsible for the other half. These calculations are done at closing, and reflected on the closing statement.
